Ouchies I'm sorry to hear that. :/ As much of a fan as I am of Google I'd always recommend going for a cheaper chinese phone. I'm planning on buying the
Star X920F which has the MTK6589T CPU (quadcore 1.5 per core), (only) 1GB RAM, 16 ROM, 12mp camera, 5", and so on... It's about the same stats as the Samsung S3 but about half of what you paid for your Nexus.
I know there's a lot of people who would be against it with the same 'old "If it's from China it's junk" but my little Xperia-clone from China, which I bought a year ago, has never given me problems and my friend with a Samsung Note 1 complains about how hers runs slow, lags, and has slow internet and is still envious of my little 1gh 4" phone.

I've seen no lack in quality or performance from mine to this day.
But ya know that's just my opinion. If it were me I'd fix it, sell it, and buy a cheaper phone with the same specs.
